Providing network services with multiple prefix delegation

With the deployment of the network services requiring special network control, such as VoIP, VPN, and streaming, it is important to configure network controlling policies according to the characteristics of the services provided on the network. If such kind of services is provided to a SOHO network, it is difficult to configure controlling policies when the number of SOHO network users increases. This is because SOHO network users request different network services, requiring different network controlling policies to be configured on each SOHO network using its IP address. To solve this problem, this paper proposes to allocate an address block per service and to assign prefixes to a SOHO network user from the address blocks of all the services requested by the user. With this proposal, multiple network services can be provided on an IPv6 network, taking advantage of its vast address space. It also illustrates some implementation examples of multiple prefix assignment using longest-match source-address-selection and multiple DHCPv6-based prefix-delegations.
